    How do Wean fry off live bbs?

    I’ve kept parents with the fry so far, and did not make any special effort to wean the fry off live BBS, since my adults all take BBS as part of their diet. The fry eventually figured out how to go after the adults’ frozen and dry foods as well. They take mostly frozen, and only get dry twice a...

    Water Changes

    I think if the water is similar by feel, the temperature is close enough to use, especially if the water change is small. I have an IR thermometer for the kitchen that I use to spot check. Though it’s not necessary to be this precise, it is a really easy way to get it exactly right by adjusting...

    Nijesseni spawn vs cockatoo - question on egg hatching

    TDS is linear, so If you're confident in that your tap is TDS 100 and your RO is near zero, you can accurately predict the result of mixing the two. That said, tap water can fluctuate and RO units have varying levels of efficiency based on method, age of membrane, etc. The simplest way to...

    Nijesseni spawn vs cockatoo - question on egg hatching

    pH shock isn't really a thing if you're talking about soft water. i.e., the pH of soft water will always fluctuate, sometimes by a lot. The only danger is going from high hardness to low hardness, which can lead to osmotic shock in the gills.

    Which peat or sphagnum moss to use to low pH?

    I have to admit I'm not well versed in this debate, but I do believe the sustainability question is controversial. Peat may continue to be produced naturally, but the argument I've read is that once a bog is mined, that bog is no longer producing normally. So the current rate production would...

    Which peat or sphagnum moss to use to low pH?

    I don't recommend that. I used to use buffering salts to lower pH, but the problem is that you increase your total conductivity. In that situation, my fish were OK but did not show any breeding behavior. Once I lowered the overall salt/ion concentration, they started to breed like crazy. Peat...

    Apistogramma cues and biotope management

    I just got a copy from abebooks. There is at least one other european seller out there (I think Netherlands). If you’re in the states, will probably run you around $100 after shipping.

    Macmasteri or Veijita?

    I personally think Macs are prettier.

    Macmasteri or Veijita?

    A number of individual breeders these days have F1 viejita from Puerto Gaitan.

    Macmasteri or Veijita?

    You don’t usually see that much red on a viejita’s body. There are more definitive markings to look at, but it looks very classically like a macmasteri to me.

    Which peat or sphagnum moss to use to low pH?

    The kind they sell for reptiles usually comes in very small quantities, so it’s quite expensive per unit. I’d get one for gardening, which will come in larger sizes and is cheaper. Just make sure it doesn’t include added fertilizers. Peat pellets also work. Finally, there are concerns about...

    A. Cacatuoides Begginer Questions

    They do not school, but tend to work better in larger numbers. If you're prioritizing the pencilfish, you'd want 5 or more. If you're prioritizing breeding the cacs, it's fine to have just 2 or 3 pencilfish. Of the two species you mentioned, the beckfordi are generally cheaper than the...

    One of my apistogramma

    If anyone has a lead on whether Koslowski is available for close to retail, I’d love to know. Saw a used one listed, but it was $400.

    Sick cory?

    Darrel is 100% on my list of "must read." I didn't know about PlanetCatfish but will definitely join, thanks for the tip!

    Sick cory?

    You can hang a net breeder in the main tank or set up something similar with a tupperware container to allow flow with the tank. Corys tend to eat their eggs, which is why people separate if they want a good survival rate. I've never raised fish from eggs before but lots of folks here have and...
